1.3. Battery lifetime extension

  • Ensure a suitable temperature - ideally around 20 ° C (high temperatures harm more than low temperatures).
  • Limit the size of the window used - do not charge to 100%, avoid deep discharge.
  • Limit the maximum charging voltage.
  • Limit charging current - frequent use of fast charging significantly speeds up battery aging.






Low temperature

  • Charging Li-ion below 5 ° C by limited current, charging in frost is not allowed.
  • Fast charging in the range of 5 - 45 ° C, but preferably 10 - 30 ° C.
  • Charging in the cold damages the battery ("plating" the anode with lithium, permanent, irreversible changes).



High temperature

  • High temperatures are not good for any type of battery.
  • Batteries are usually not charged at T> 50 ° C to avoid accelerated aging.
  • Limit charging current, charging with high current at high temperature reduces the capacity of the battery. Moreover, it may cause gas production and inflation.
